Table 8-1 summarizes the Fourier series quantities for the circuit of Example 8-1.
As the harmonic number n increases, the amplitude of the Fourier voltage component
decreases and the magnitude of the corresponding impedance increases, both resulting
in small currents for higher-order harmonics. Therefore, only the first few terms of the
series are of practical interest. Note how the current and power terms become vanishingly
small for all but the first few frequencies.
